Abstract
Ultrasonic imaging in B echography requires high resolution over the entire scanning zone. Phased array transducers in conjunction with analogical shift registers (CCD) allow sector scanning and dynamic focussing. Working within this framework a measurement instrument has been devised to evaluate the influence of the different parameters on the image.
